Size Guide

We design with 4 mm of growing room in every garment. If your child is between two sizes, size up — our fabrics keep their shape through every wash, so a piece that fits a touch loose at 6 months will fit perfectly at 9.

How to measure

• Chest / bust — fullest point, tape level all the way around, two fingers of room.
• Waist — natural waist (where the body bends sideways), not where you wear jeans.
• Hip — fullest point at the seat, tape parallel to the floor.
• Kid height — barefoot, against a wall, mark and measure.
